MAP 1020: Problem Determination
Purpose of This MAP
Use this MAP to get an error code if you were not provided one by the customer or you are unable to load
diagnostics. If you are able to load the diagnostics, go to MAP 0020 in the
RS/6000
Eserver
pSeries
Diagnostic Information for Multiple Bus Systems .
The service processor may have recorded one or more symptoms in its error log. Examine this error log
before proceeding (see “System Information Menu” on page 376). The system may have been set up by
using the HMC. Check the Service Action Event (SAE) log in the Service Focal Point. The SAE log may
have recorded one or more symptoms in the Service Focal Point. To avoid unnecessary replacement of
the same FRU for the same problem, check the SAE log for evidence of prior service activity on the same
subsystem.
The service processor may have been set by the user to monitor system operations and to attempt
recoveries. You can disable these actions while you diagnose and service the system. If the system was
set up according to the recommendations of the
Eserver
pSeries 630 Model 6C4 and Model 6E4 User’s
Guide , all the settings of the service processor (except language) were saved by using the
SAVE/RESTORE HARDWARE MAINTENANCE POLICIES service aid. You can use the same service aid
to restore the settings at the conclusion of your service action.
In case the service processor settings were not saved by the user, if you disable them, make notes of their
current settings for restoration before you leave.
In addition to the parameters in the following table, you can disconnect the modem to prevent incoming
signals that could cause the system to power on.
Following are the service processor settings. The service processor menus are described in Chapter 7,
“Using the Service Processor”, on page 363.
Surveillance From the service processor Setup Menu, go to the
Surveillance Setup Menu and disable surveillance.
Unattended Start From the service processor System Power Control Menu,
disable unattended start mode.
Reboot Policy From the System Power Control Menu, go to the
Reboot/Restart Policy Setup Menu and set:
1. Number of reboot attempts to 0 (zero)
2. Use OS-Defined restart policy to No

Call-Out From the Call-In/Call-Out Setup Menu, go to the Serial
Port Selection Menu and disable call-out on both serial
ports.
